MULTI-LAYER STRUCTURE, INNER LINER FOR PNEUMATIC TIRE, AND PNEUMATIC TIRE

摘要

The purpose of the present invention is to provide a multi-layer structure which has high gas barrier properties, high crack resistance and excellent fatigue resistance, and to provide an inner liner for pneumatic tires which uses said multi-layer structure, and a pneumatic tire provided with said inner liner. This multi-layer structure is provided with barrier layers (2) and elastomer layers (3) is characterized in that ((U1+U2+ ... + Un)/T), the ratio of the thickness occupied by the elastomer layers (3), is 60% or greater.
